INDICATING COPY-HOLDER.

SPECIFICATION forming part of Letters Patent No. 679,302, dated 1 uly30, 1901. Y

Application filed August 27, 1900. serial No. 28,219. (No model.)

To all whom it may concern.-

Be it known that I, EDGAR A. EDWARDS, a citizen of the United States,and a resident of Cincinnati, Ohio, have invented certain new and usefulImprovements in Indicating Copy- I-lolders, of which the following is aspecification.

My invention relates to indicating copyholders of that class adapted tothe use of copyists, type-writers, and others; and the objects of myimprovement are to provide a platen with a clamp to hold the copy andwith an indicator actuated intermittently by the operators hand throughadjustable lever mechanism to indicate the lines of the copysuccessively. These objects are attained in the following-describedmanner, as illustrated in the accompanying drawings, in which Figure 1is a front elevation of my device; Fig. 2, a side elevation; and Figs.3, 4, 5, and 6 details of construction.

In the drawings, 8 represents a platen or plane surface, preferably ofmetal and mounted in a slanting position on metal base 9 The feet of thebase are provided with rubber tips, and a vertical column 11 is extendedabove its middle portion. Clamp 12, formed of springwire, is secured tosaid column andextended: over the top of the platen to hold the copy inposition thereon. Coil-spring 13 is attached to one side of the clampand terminates at one end inarm let, which is adapted to retain theleaves of the copy in position after they have been copied and turnedupward over the clamp and under said arm. Guiderod 15 is secured a shortdistance from one edge of the platen to brackets 16 and 17, that projecttherefrom, and rod 18, parallelwith the guiderod and located fartherfrom the edge of the platen, is movable in bearings formed in thebrackets. Carriage 19 is arranged to slide on the guide-rod, which isextended through an opening formed therein, and tube 21, formed on therear of the carriage, communicates with said opening. Slotted bracket 22projects from the front of the carriage and arm 23 from its side for themovement of the rod through an opening formed therein. Notches 24ar'eformed in the front and rear of the carriage, and lever 25 isloosely hinged or fulcrumed therein by means of prongs 26, that projectfrom one end of the lever. An open ing 27, formed in said lever, permitsthe rod to move freely therethrough when it is lifted by the rod in itsupward movement, but grips the rod in its downward movement and locksthe carriage thereto. The gripping action of the lever on the rod ismade more positive by the expansion of spring 28, that encircles the rodloosely between the lever and arm 23.

A plug 31, preferably of leather, is inserted within tube 21 underspring 32 therein and in frictional contact with the guide-rod, andscrew 33 is adjustable in the end of the tube and against said spring tocontrol the frictional resistance by the plug to the movement of thecarriage by the rod. Finger 34 is hinged on bracket 22 by means of bolt35 and is adjustable thereby to the extent of the slot formed in saidbracket perpendicular to the plane of the platen to adapt it to copiesof different thickness. ably of leather, is interposed between thefinger and the head of bolt 35 to maintain a constant frictionalresistance to the hinge movement of the finger on the bracket in a planeperpendicular to the platen to facilitate the placing of the copythereunder. Handle 37, formed with gap 38, is secured on the lowerextremity of the rod, and spacing-lever 41, fulcrumed at an intermediatepoint on lug 42, that depends below the platen, engages at one end withthe gap in the handle to actuate the rod in opposite directions. Thedownward movement of the lever is effected by the hand of the operatorand its upward movement by means of tension-spring 4.3, which is securedat one end to lug 44;, formed on the lever, and is adjusted to differenttension by the engagement of its other end in the different holes 45,formed in the column of the base.

Differential stop 46 adjnstably limits the stroke of the rod in anupward direction by the contact of handle 37 therewith. Said stop isformed with two points of contact for the handle, the one being at 47near one of its ends, the other at 48 in its middle portion. The rearend of the stop is hinged at 49 on cross-bar 51, which is formed onbracket 17, and it is vertically adjustable at its front end by means ofadjusting-screw 52, which is located in the front portion of saidcross-bar. Lip 53, formed on the rear end of the stop, de-

Washer 36, prefer pends below the pintle of the hinge, and back spring54, secured on the cross-piece, exerts sufficient pressure thereon tomaintain the front end of the stop in contact with adjusting-screw 52.In the various positions of adjustment of the stop the stroke of the rodmay be differentiated in a predetermined ra tio proportionate with thedistance from hinge 49 of the point of contact on the stop of the handletherewith. If the point of contact 48 thereon is midway between point 47and hinge 49, then the contact of handle 37 with point 48 thereon limitsthe stroke of the rod to onehalf the length of the stroke permitted bythe contact of the handle with point 47. Collar 55, secured on the rod,limits its downward movement by contact with the top of bracket 17. Itis formed with two fiat sides that form a right angle and terminate instops 56. Spring 57, secured to bracket 17, extends in an upwarddirection adjacent to the washer and one of the stops thereon totheextent of the stroke of the rod to prevent it from rotating. By means ofthe handle the rod may be given a quarter-turn to bring the other faceon the washer and its corresponding stop adjacent to spring 57, wherebythe handle is maintainted in registration with the corresponding pointof contact on stop 46 to per-v mit the rod to make either a full strokeor a half-stroke.

In operation spacing-lever 41 is depressed by the hand of the operatorto overcome the resistance of spring 43 and drive the rod in an upwarddirection, with handle 37 in contact with stop 46. By relieving thepressure of the hand on the spacing-lever the tension of said springreturns it to its normal position of elevation and moves the rod in adownward direction, with collar in contact with bracket 17. During theupstroke of the rod without resistance through spring 28 and through theopenings in arm 23 and lever 25' the carriage is maintained immovable onthe guide-rod by the frictional contact of plug 31 being sufficient toovercome the frictional resistance of the carriage on the guide-rod. Inthis manner indicating-finger 34 is intermittentlymoved through a seriesof equal spaces from the top to the bottom of the platen, and the widthof the spaces may be regulated to cause the indicating-finger tosuccessively register with the lines of the copy by the verticaladjustment of stop 46. When the indicating-finger is adjusted toregister with the lines of single'space type-written copy, the handlemay be turned from registration with point 48 on the stop intoregistration with point 47 thereon to adapt it to double-spaced copy.Lightly tapping the spacing-lever will cause the carriage to crawl alongthe guide to register the finger with the first or any other line of thecopy. Lifting locking-lever 25 disengages it from the rod and permitsthe carriage to be moved thereby to the top of the guide, with thefinger at the place of beginning of the next page of the copy.

Having fully described my improvement, what I claim as my invention, anddesire to secure by Letters Patent, is

1. The combination with a carriage frictionally movable on a guide, afinger adjustably hinged thereon, a rod reciprocated by lever mechanism,and locking mechanism on the carriage arranged to automatically engageand disengage the rod in its respective move ments in oppositedirections, ofa differential stop, a handle secured on the rod andmovable into positions to be carried by the rod into engagement withdifferent points of contact on the stop, and means to adjust the stop tolimit the movement of the rod.

2. The combination with a rod actuated by lever mechanism, of adifferential stop, means to adjust the stop to change the length of thestroke of the rod, a handle secured to the rod and movable intoregistration with different points of contact therewith on thestop,whereby any adjusted length of stroke of the rod may be changed ina predetermined ratio.
